You got a very helpful weblog I've been right here reading through for about an hour or so. I'm the beginner as well as your achievement is extremely a lot a good motivation personally. red light xbox repair

I always use grad ND filters for sunrise & sunset. The greatest software in the world cannot bring back burned out hightlights. Neither can it reduce the glare that a polarizer can when shooting refective surfaces. I also use solid ND's for shooting waterfalls.

My lenses are almost always covered with a polarizing filter (unless there is an extremely low light situation). I also carry around several graduated ND filters in my vest pocket for those times when the contrast range of a scene is so great that the camera's histogram spans the entire range from whites to blacks.

I use ND and polarizer filters from time to time for effects I know of no software for. For instance, removing glare and capturing details beneath the surface of water or emphasizing the flow of a waterfall in brighter than ideal light.

You can't "imitate" the effect of a polarizer, and if you want a long exposure to, say, blur moving water, you may need an ND filter to avoid overexposure. It would be nice if DSLRs had really low ISOs available - like 5 or 10 or even 1, but I doubt this is compatible with how the sensors actually work.

I need more control than I can get with "built in" ND filters. Adding or taking away levels of ND filtration gives me the control to get those Ghostly water images. A polarizer helps with just about any thing!

As a landscape and nature photographer... the polarizer is a given for lenses other than ultra wide angle. 2-stop ND works best on my Tokina 11-16mm lens. For the UW Tokina, the polarizer works on special occasions only.

I mostly use a circular Polarizer. I shoot a lot of desert shots and nothing pops that winter blue sky like a good polarizer. The only time I don't use an ND outdoors very much as my camera has a pretty low ISO for the bottom. But I do use an ND in the studio, in fact sometimes even a CP to reduce specular highlights and reflective distractions on glossy surfaces.
